Car valuations and market reports, inside ChatGPT and Claude

MarketCheck AI Desk sells finished vehicle reports and raw market data inside Claude, ChatGPT or any MCP client. Give it a VIN, a ZIP or a dealer website and it returns a valuation, a window sticker, a total loss or diminished value file, or a lot scan built from dealer listings. Every market price is an advertised asking price.

Free to add. Reports from $0.50 each, $25 minimum top-up. Prefer the browser? Sign up and run reports on the web.

Reports by desk

Pick your line of work to see the reports built for it.

VIN-by-VIN valuations defensible to clients and lenders. Comparable evidence, market position, history red flags.

Appraiser Desk

Raw MarketCheck data, priced per call.

Reports give you the finished read. These tools give your AI assistant the raw data underneath, billed per call from the same balance. Ask directly ("show me Rogue listings under $20k near 84070") or as a follow-up to a report, without running it again.

All data tools

Included in the connector: the Market Data Tools are selected by default when you connect. Starter rates per call (Sold Market Data by the shape of the question), charged to your balance only when a tool is called.

Three steps. No code.

  1. Add MarketCheck to Claude or ChatGPT

    Paste one link into Claude or ChatGPT. It takes about 30 seconds.

  2. Add starter credits

    Your balance is real money, not abstract credits. Reports start at $0.50 each, with a $25 starter minimum. Auto top-up keeps you running, and unused balance is fully refundable.

  3. Ask Claude or ChatGPT a question

    "What's this Camry worth?" "Scan my lot for under-priced cars." "Local market for SUVs in 60601?" Your assistant pulls the report, narrates it, and charges your credits.
